Good point. And even more so. What I think we would like to have is:
(1) Read access to the raw output of the entropy source.
(2) Possibly read access after whitening.
(3) Write access to inputs of the PRNG
This would allow us to probe that the whole chain works as intended with
KATs for the PRNG part.
This would still not prove that Intel, when MUXing in data from (1)/(2)
into the PRNG actually does something completely different.
